to get the answer just take number of moles you have and multiply it by the molecular mass of the compound which is 22g/mol in lithium oxide's case.
23mol x 22g/mol = 506 g of Li2O
1 mole of lithium has a weight of 7g so, 3 moles weigh 7 x 3 21g
To determine the grams of lithium hydroxide present, you need to use its molar mass. The molar mass of LiOH is approximately 23.95 g/mol. Therefore, 3 moles of LiOH would be: 3 moles x 23.95 g/mol = 71.85 grams of lithium hydroxide.
The molar mass of CuSO4 is 159.6 g/mol. To find the mass of 3 moles of CuSO4, multiply the molar mass by the number of moles: 3 moles * 159.6 g/mol = 478.8 grams. Therefore, there are 478.8 grams in 3 moles of CuSO4.
To determine the number of moles of lithium in 20mL of 0.5mM lithium phosphate, first calculate the moles of lithium in 1mL of the solution: 0.5mM = 0.5 mmol/L = 0.5 × 10^-3 mol/L = 5 × 10^-4 mol/L Now, for 20mL: 5 × 10^-4 mol/L × 20 mL = 0.01 moles of lithium
The molar mass of ammonia is about 17 grams, so that 3 moles would have a mass of 51 grams.
1 mole of lithium has a weight of 7g so, 3 moles weigh 7 x 3 21g
380.7 grams of iodineis equivalent to 3 moles.
4.3 moles of AI(CN)3 have 451,5 grams.
54,0 grams of water is equivalent to 3 moles.
15g Li * (1mol Li / 6.941g Li) = 2.16 mol Li
3 moles of calcium is equivalent to 120,234 g.
